My fan made Pokémon named Tentacotta (Octopus Tentacle and Terracotta pot). He is an Agave octopus in a pot. He is based on land warfare/the military and is a grass ground type. Any way to improve it?

Yes I know it it had a weird texture for the pencil, yes I know it has no shading, this is not the final version. If you’ve seen this on this sub before, it is because I am working with someone on a region. The final evolutions of the starters are based on land, air, and marine warfare. Would this work as a grass starter?
