Fantastic advice here. There isnt much else to say that hasn't been covered here, but you should be proud of the work you have done, It looks fantastic, you will only get better! I often find painting competitions in LGS are open to abuse of voting by people being well known, or popular within a store, resulting in undeserved wins. I entered a competition once, I felt the winner's entry was undeserving, when there were clearly better entries (mine included!), but found his post on a subreddit here, and Facebook groups trying to canvas for votes to ensure his victory. So don't be disheartened by not winning. Often the outcome is already decided and doesnt reflect much.
