I like the deoxys but it looks kinda cluttered.
the numle is pretty cool i like the concept.
And i have 5 fusions(2 of which are the same but with different ears) that me and a friend just finished working on.
PIEQUAZA!!!!
Salacoal + and Glalamanix
Alright, so your first one the Pichu with Rayquaza Head, doesn't look too bad though you may want to fix the location of the head since it looks like it is coming from one of the ears, also I'm not sure what's up with the Beedrill drills, they are very out of place and obvious add-ons, they don't really fuse with the rest of the creatre but yeah this one is pretty good.
Your second one I really don't like, there has been very little chanced to it aside from the various Crobat Wings, Hair, Inserted Beedrill Drills and Pichu Ears it really looks like you are just trying to make Raquaza something it isn't.
Your third I like, though still not very different from Rayquaza, it at least looks like it is going somewhere. If you were to further Edit this one so it looks less like Rayquaza but following that hair theme I think you could get some really good things from it. Also I suggest fixing those bottom front wings the Blue doesn't work.
Honestly I'm gonna essentially say this right now, My Deoxys Fusion is as clustered as this one. I like it, I really do, you've used an excellent combination of pokemon here and the colouration is brilliant. My recommendations are to adjust the wings so they are coming out of the holes in the shell, replace the ears, honestly Baby Pokemon Ears never work on Power Pokemon.The steam is probably the best part about this though because it is so well co-ordinated with the mouth and shell. Overall an excellent piece of work which can go further.
This last one, I'm saddened by it, this did not have nearly as much effort put into it as anything else I've seen from you. You can't just size up Pokemon Parts to make them fit together, you have to edit them to work. The Salamence Wings, Onix Body and Haunter Hands all suffer from this, you need to re-edit the entire sprite if you want this to work. The only saving grace in this sprite is its head, which you have done some reasonable fusing of parts but like the Rayquaza Sprites it suffers from looking too much like Glalie, this is not a good Fusion at all, I'm sorry to say. One last thing, If you want the Onix body to move in different directions such as horizontally so it looks as though it is flying or vertically down as though it is looming, I suggest taking multiple Onix sprites and fusing the rocks together for this effect. I did the same on my Blue Smoke creature around the side rocks.
Overall I suggest editing the 3rd and 5th sprite, the fourth is almost perfect but just avoid the first and 2nd they won't get you anywhere.
Anyways, got one hell of a cluster here, so prepare yourself for a fusion of 16 Pokemon all Grass-Types, this creature takes sprite from many evolutionary families made up of Grass-Types, I'll list them below the sprite.
Pokemon Involved: Ivysuar, Venusaur, Oddish, Bayleef, Bellossom, Grovyle, Nuzleaf, Shiftry, Cacnea, Tropius, Wormadam (Grass), Carnivine, Servine, Sewaddle, Lilligant & Deerling.
