I'm just gonna post all of my pics now:
Your improvements are amazing. I'd like to see you re-do the pikachu-lucario fusion now that you know how to sprite better.
When I first started I didnt even know to uses sprites! It was horrible, my first fusion was a porygon with a psyduck bill haha, and I used Sugamori art, it was a fail. but the more you do the better you get. and it looks like you've got recoloring down! thats one of the hardest things to learn! Im gunna keep watching your progress...My favorite is your Yeti BTW it is just awesome!
Recoloring is pretty easy to learn.
I would say the Yeti Slaking is the best re-color- the colors work well (sometimes white can be a bit of a hassle to work with) and there isn't any missing pixels from the outlines. However, talking about missing pixels from the outline, Red Feraligatr has gaps where the pixels should be- the cause of this is most likely to be when you are recoloring inside, you go over the whole body and it will also recolor the pixels on the outline.Make sure that when recoloring every color has a different recolor- even if the original colors are very similar. The Black Ledian has small lump of white pixels by it's eye, whilst the Meowth Green color looks strange on it- I would think coloring it with a lighter green would be better. But otherwise, diffidently an improvement from your older sprites.
Hmm...regarding your Pikachu/Lucario fusion and your Fire Bulbasaur, you shouldn't resize the sprites. As you've been told before, it makes the sprites look blown up and not very aesthetically pleasing. It looks messy and bad, and we don't want that. Try taking a look at a few tutorials, you'll find lots of good tutorials that explain good techniques on how to successfully sprite. I'm guessing those were your oldest sprites, though, because your recolors are a big improvement.
I think I've noticed a small pattern in those sprites, though. The Ice Infernape and Red Feraligatr have mismatched outlines. Infernape still has some of the original red/orange/brown outline from the official sprite, and the Feraligatr has red outlines on its white scales, which shouldn't be there. You could use a light gray instead. Also, there's a lot of black on the outline which makes it look...well, bad. Try using a dark shade of red where there shouldn't be black (rules of light source and whatnot, you can find more detailed explanations in tutorials and stuff since I'm really bad at explaining these kind of things lol). The Yeti Slaking has the same problem with the black outline, but it's very good and it has a creative idea behind it. Again, use a light gray or a darker icy blue for the outline where it needs to be used.
The Black Ledian and Green Meowth are good, but again, upon closer inspection, the Black Ledian has leftover red outlining. Fix that by using black or a dark grey and it should be good to go.
I'd love to see more of your work as you improve!
