I used to make sprites that, now, I'm ashamed of (as they were, to be blunt, awful) and have since deleted them from my hard drive...FOREVER. But that's not the point. I've made some random sprites for want of something better to do, and some constructive (OH GOD PLEASE JUST CONSTRUCTIVE-- NO HATING) criticism would be nice.
Front and back sprites of a Bulbasaur, recoloured using just the three colours of the flower on Venusaur's back (brown, yellow and pink).
A pokeball with Eevee features.
Two palette swaps: Plusle with Minun, and Aria Meloetta with Pirouette Meloetta.
A sort-of Meowth/Eevee splicey-thing. Not sure what to call it. Definitely not my best, though.
I'm not even going to pretend to call this 'Pikablu'. It's just a corrected palette inversion (not counting the eyes).
Kind-of average splice practice; Mudkip with Treecko and with Torchic (plus Cyndaquil).
Two of my RP characters; Theodore the Meganium and Chase the Chikorita, both with palettes for comparison to the original.
A random recolour of a Snivy. Does this count as a sprite? I'm not sure...
My favourite one, a fire-retyped Feraligatr. Not sure why I like it, though.
EDIT: More sprites
Basculin palette swap.
Delibird palette inversion.
Inspired by the Pikachu-coloured Pichu, this is the Snivy-coloured Serperior. One problem with it is the difference in number of colours between the two palettes, so the lighter green area is actually Serperior's palette from what is now the richer green area.

Recolour of the Striaton Brothers in all their forms. This took an epically long time to do.
An Espeon/Umbreon palette swap. A far cry from my best work, I think.
Just thought I'd throw a random playing card in there, too.
Two more RP characters- Ciôn and Sin, from SonsOfAdmirals' Becoming a Pokemon.
