Ahh... welcome to the world of scifi kits.
here you will run accross something that is... sort of lacking in most other genres, except on aircraft and a tiny bit on figures.
SEAMS!!!!
When working on scifi kits you really need to take time, a lot of time making sure you seams are filled. You missed quite a few, most prevalent are those on the nose of the kit, as well as some allignment issues that are in the molding, it could be fixed but would have been ALOT of work.
Also, with all scifi remember the second major issue people forget, and is NOT prevelant in any other genre except for ships
SCALE!!!
Your ship there is a MASSIVE ship, in a very small scale. Any weathering you do, like your pannel lines, has to reflect that, the shadow of that Corner would not be as dark as you have it.
I would suggest if you want a CLEAN pannel line, to either use a paint marker with a fine tip, like the gundam marker designed for pannel lining, or something like a pencil then dull coate it.
you could also go the rout of using washes and wiping off all except the very inside crack.
On the cockpit part im not sure if you tried to pannel line those thick stripes or color them, it looks sort of like both, in the future decide one or another.
If you wanted to get fancy you could even take the base coat, put a drop of gray in it to darken it just a bit, and do the recessed areas in the darker color to give it a textured appearance as to break up the monotony if your keeping them unfilled in.
Remember the scale though, a kit 1/110 is very small a person in that scale is less then half an inch tall, keep that in mind when you weather and detail. Look at the shading and lining you did and imagine it 110 times larger, does it seem realistic to you then? if not, re do it
