Hello and welcome to the Shipbucket.
It's a perfectly decent drawing, and I don't see any really serious issues with it.
Design-wise I probably wouldn't want to fly it, because it just has a feel
of having funny flight characteristics, but that's just it.
Drawing-wise, the leading edge of the vertical stabilizer looks strange and shading suggest it's almost as wide as the fuselage in the center and has two deep cavities (?) in it. Speaking of fuselage - the "brighter" stripe along the top edge looks too wide and suggests that fuselage doesn't get more narrow towards the tail. Also, the tail wheel strut and propeller blades look bit crude. And as for the camouflage - IMHO colours are too intense, but on some old FD drawings people used similar ones (maybe try to use shades from someone's relatively-recent drawings).
That said, it's generally a promising work and I hope to see more of Your drawings in the future.
