It's a nice painting with a somewhat mystical fibe to it.
I like the use of the colours but it could have a bit more variation to make it more realistic and to create more depth.
I don't know if i would call this a technical drawing since there aren't a lot of technical difficulties visible i think. Maybe you could use more shadows and highlights, maybe in combination of some textures, to make it a more believable scene.
Still, i like the setup and the overall setting of this piece, keep up the good work and keep painting!
huh, i didn't know what technical drawing meant, thanks for the info. As for the shadows and highlights, what areas do you think it needs more attention? I want to get more tips on doing these lineless coloring :3.
