First of all, this should probably go in the General Spriter's Showcase
, since there's not that many sprites to make a whole thread.
Second, are you saving in .PNG?
Not bad, but the outlines of most are a little off, like, they're the same colour as the body of colour, and some have random chunks out of them...
The octillery one needs shading on it's head, but the way you fused it is ok.
Not bad for a first time, I remember I wasn't so good when I started.
