Are you kidding me...that is not bad at all...not at all. You are working on your technique...and it is technique that helps distinguish a good modeler from someone who just throws them together..for the sake of getting it done.
If I may.....can I offer a few suggestions?
One..never tear parts from the runners..always cut them off with ample left overs..so you can cleanly hand trim and sand the sprue clean...leaving no sign,
Only remove the parts you need at the time and cut away excess sprue so they do not clog your work area.
Try masking...especially when painting along long lines or up against 90 deg angles. I use a roll of fine painters blue tape...I cut with a hobby knife a thin strip all the way around the roll....allowing me to have a nice narrow strip I can roll out as much as I need. Then you can mask in tight spaces..giving you those crist paint lines.
Here is one more..just for fun. On many wooden ship models..they come in molded brown..but the hull needs to be a darker or lighter brown...don't bother painting the highlighted areas...simply draw your hobby knofe across the raised area..removing the paint and revealing the other color......sharp..looking and very easily done. It can be messy...but paint dust is easy to deal with..then squigly over painted areas.
With these simple techniques in hand..you can master even the toughest paint job...:)
