So far so good I'd say :) You're defs improving your skills, but you have been already improving TONNES before you took the challenge. You're best 2 photos so far would have to be "Passing Time" and "Meh", then probably "Untitled" and probs... "Anatidaephobia". You're finding good compositions and focal points and your editing is quite good. However, you're a lot better at macro than things such as portraiture and you have to watch the angle you take a photo at or what's in the background. Also be careful to edit things too much at the risk of things becoming over done. Otherwise I'd say your quite talented and your photos so far have been fantastic :) You just need to experiment more with your camera and be more open and imaginative with subject matter.
