Look we all began our first models at some point being anewbie and not knowing all these techniques previous posters here stated.

Reaper goodjob im assumeing this is one of your first models? i remember my first and looked similar , since i had no idea about how to weather or paint chip the vehicle ect.. the more you build the more experience you will get trust me. ive been dabbing in 1/35 scale armor on and off for 10 years and i still dont think i do a great job with my models.

here is my first model i did a few weeks ago first one i did in almost 2 years.

Do some research on the idea you want to portray look at the real vehicle in real life how it looks how it looks weathered and worn, get the right tools. Modeling tools(painsts, pigments, washes etc..) today make its SO much easier to make your model look professionally build and painted then ever before.

also look online at tutorials on how to do certain techiques like paint shipping, white wash , rust etc.. theres hundreds on online sources that tell you step by step on how to do these things.

last but not least, take these critisims as help and not as were being Aholes to you people here generally want to help others inprove.

Another thing  is that this being a Stug IV is needs Zimmerit unless you're building a late production vehicle but it doesn't seem like it is from the 4 return rollers and the single muffler on the back.

There's alot of work that was left off and it apprears you didn't even paint it at all and just put decals on i it and even those were put on crooked.  Idk how old you are or what your skill level is but you at least need a painted camo scheme and painted tool detail.  

Adding in those extra details is what makes your subject go from basically a toy to a work of art.

A clean build for sure!  If that was what you were going for then you got it.

A couple things I noticed....your road wheels are not painted.  Also the tools need painting too.  I am also curious what paint you used for your base color for the tank.  Was it a gloss paint or did you use a gloss coat to put down decals?  I ask because it has a pretty glossy look to it that could use a good flat coat to kill the shine.

Looks better than my first dio! 

And my second...

and my third... 

and well, let's stop while we're ahead here eh?

If I may make a suggestion one of the most useful sources I found on the subject was Shep Paine's 'How to Build Dioramas' - the book is a little old and slightly outdated in a few areas but it's still well worth every penny I paid for it. Lots of tips both for building tanks and the dios you set them in. 

REAPER1770  Good way to start. The paint color is uniform and doesn't look splotchy,dippy or runny. The figures are well placed, looking at each other.The size of your base is good, as it gives the whole tank a place to sit, and not look as if it is going to fall  off, or coould be repositioned for a change if you want. The markings don't show any silvering and though they can't be seen well, the tracks look to be a good basic "trackie color".

 The grass is green,

the sky is blue

an this dio is all right for you.   Oww Sorry.

Can this project, and the next one, be improved? Yes

Can you improve it and get better ? Yes

Will you get better? Yes

Continuing to try and get better at things while adding new things to your skills will make you and your builds better each time.

Don't forget to ask questions as you build a project. Share pictures as you go so others can chime in with ideas, suggestions, thoughts to help you improve.

Now Go build something   

well the idea of the tank was that it was brand new

Glad you enjoyed that classic Tamiya kit.  You might pay more careful attn to the directions on parts placement next time. I see you closed off the gunner's periscope with a fitting that's supposed to be a tow hook mount.  Also on the right fender is the commander's scissors periscope.  If not emplaced, it would have been stowed inside.  Hope these help.  Keep posting pics!

IMO, the tank is too clean. Tanks in the field/action are dirty with bits of soil, grass. dust, mud, footprints etc stuck on them. The grass is also too "manicured", unless we assume that the tank is the first one to arrive to this field.

Just my Canadian .
