RE: my first sprites ever!! any tips on how to improve?
They're ok, but you didn't re-color any of them. Plus, the Galladetune only has on of Tune''s feature's. However, they're very good for you're first sprites ever.
Combee fushion: Not bad, could use re-coloring and make it appear more like it WAS fused with Drifloon.
Magnezone thing: Needs re-coloring...
Piplup+Infernape: You could re-color the flame, but looks good.
Gallade+Tune: Needs more of Krickitune's feature's and you could slightly re-color it..
Very nice for your'e first try, though!
