Salazar one. What you do right now is just putting a lot of stuffs in a sig together, using the largest space available. Let me tell you a little trick; smaller your sig, easier it will be. Beginners often get the impression larger your workplace, easier it will be; wrong. What happens is that they get too much space and want to fill it with as many fancy stuffs as they can.
Use a smaller cramped space, and you'll wish to put less but more significant things in a more orderly fashion.
For instance, Shalazar' OC Dreadnaught should be removed altogether. Not only dont we see it completely, it is a poor quality render.
Make things blend with each other. Right now, nothing blends together. You have this weird background which colours doesnt fit with each others, along with multiple other stuffs that really doesn't merge well with each other - among others, I really dont like Mr Bond' funnily cut-off head....

Also, we get our background from google, or we make them ourselves.
I like to use space render from google or in game, or industrial futurist close up of buildings. with the right keyword, everything is possible.
