ive been a 3d artist for like 6 years now and i was pretty good at 3d after 6 months of youtube tutorials, all you need is to just have a decent workflow you know like know what is proper topology for hard surface and organic surface, how to uv map and texture, blender is amazing at texturing btw, also try to find an easy and simple artsyle for your game that is very pretty and works well with your gameplay.
also here is proof that i know 3d very well https://www.artstation.com/gloriatheanimator
i even work as a full time freelancer nowadays taking commisions for animating modelling and recenly even got into 2d concepting
you just gotta keep at it and dont give up
there are so many free tutorials and supportive people in the blender community that you can easily learn the program to a really nice deegre within 6 months and it is SUPER SUPER WORTH IT cause you can always use this skill for other projects and ofc maybe even find a some work related to it if you are ever low on money
i woulnt call my self a creative person i just kinda copy what already exist but in my own unique way
cause its really hard to make a pixel perfect copy
everything is an interpotation
-ps sorry for my bad spelling i am working on that
