The two (self-admitted, I might add) things I would work on first?
-Decals (the whole clear gloss/decal/clear gloss/clear flat process- not that hard, just tedious.)
-Painted canopy frames. A bit harder to do, but it's something to work toward.
On the other hand, you paint job is certainly commendable under ANY circumstances, first model or not. From what I've seen this is the hardest thing that beginners have to get a hold of. But you don't look to have any problem with it at all.
What does this mean? Two or more projects (with some new small tweaks and new techniques each time) and I think you'll suprise yourself.
Is it a bit rough? Yeah. But it bodes well for the future. REAL well.
I'm eager to see more. Good job!
