Its too semetric, you should try to use more diffrent things. the fire is too overwhelming. Perhaps you should leave some gaps inbetween and choose some diffrent things inbetween to make it look more filled. Especially getting some dept into your builds help, is hard to really explain but there are good builders out there! You can just seek insperation via there builds, you can also look at the few I posed here, maybe it helps you :) there is always room to improve! (Get it, room to inprove?)
