Nice recolors, the revamps are okay too. AS for the fusion, the quality is good, but I can't really tell what you fused with Luvdisc. The only changes I see in Luvdisc are the added wings.
It's a Luvdisc / Xatu fusion, I reckon.
Now, C&C, yes....well.
The recolors are perfect really, you kept the shading, recolored the outline, saved as .png, nothing bad to say about that. The orange outline on TTar is slightly too bright, so get that fixed. The fusion is technically good, but you chose two (spriting-wise) worthless pokémon to fuse (altough Xatu has fusing potential, you could copy - by which I mean scratch - the patterns on Luvdisc. Either way, if you'd choose better pokes, it'd be good. Revamps, yes, well the shading is fine, good even. But as somebody mentioned before the outline is wrong. You fixed it with the Sandslash and the Maril looks good as well now tough. On the Marril, it's left ear (your right) looks flat, because you didn't separate it from the body, a few more pixels of body outline before the ear would fix that.
In general, if these are your first, I am most impressed. I hope I've been of help and keep'em coming .
Well, I'm new to spriting, these are my first ones ^^ I hope you like them.
Please give me constructive criticism. And tell me what you think.
Wow,i especially like the gardevoir and the kyogre,Erm..is kyogre is a colour from shiny rayquaza?lol,I think it is correct.
I love your sprites. But the Luvdisc/Xatu splice is a bit plain.
Try doing more... fusing on your fusions, however, i really like the recolors.
