Not bad for a first map indeed, but I have to agree with greaserpirate that it is very repetitive. You get lost in the map because it all looks the same. Also, all rooms are very small, which is a bit problematic imo for a fast game like RE. Another remark is that you added lights, but no light textures like lamps so where is the light supposed to come from?
