Well this is my delta maractus. Honestly, i think it looks too much like a grass type, but I didn’t really want it to be a lump of water. Its typing is just plainw ater because i noticed there was at least one delta per every type except water so i made one.
The outlining seems to be a bit off. The black lines stand out a lot more than the other colors. Try different shades of blue/green
It needs to be Water/Grass. You can’t just put water lilies on a Pokemon and say its pure Water. Even though most Deltas are a complete change of type, it should stay true to the design it has as a Delta.
The body shape is more of “sand and slime” looking more of it being “water” imo.
