None of this is in the Hedgewars style, it's merely a copy-paste of imagery from the game it's based on, and then cutting them from their backgrounds. I can understand it from a learning perspective, however. Try looking at this thread [ http://hedgewars.org/node/704 ] to understand how maps should look. Good luck.

You absolutely right about most of it (although it was a little bit more a copy-paste I tried to make an interesting dynamic in terms of the battlefield, with elevations and cover), but I enjoyed looking at the thread you link so thanks!

Part of the problem comes down to the fact my drawing abilities somewhat resemble that of a drunk gorrila escaped from a zoo, but I don't want to let that put me off from trying

Haha, don't worry, many of us have drawing skills on that level (e.g. I have), so you're not alone. Also there are always people who draw even worse (like a completely stoned penguin alcoholic), but some of them don't even realize that they can't draw XD

Avoid using copyrighted materials in maps. By not doing so your map has no chance in being officially included in the game. Look at the first TF-map and try drawing something similar using hedgehogs and not the original models (property of Valve).
