Hi Geamon, they look really good, especially for your first maps - nice work. As Mearrin says, you could work with a darker setting, and personally I think that the texture on the surrounding walls were to blurry. A good way to get your maps better is working with your shadows - those fungi are probably high and thus casts long shadows - this also gives you the opportunity to show some shapes that you can't see from above. The bodies could use a small drop shadow too ... and returning to the bodies - I'm of course not sure about the scale you're working at - but most battlemaps work at 1 inch = 5 feet - in which case your bodies are about 4-5 feet tall?
But good going, post the next ones in the WIP section so we can help you improve ... and have some rep with my mace of nice repping +5
