First off Welcome to GTP! For your first photos they are pretty good. The angles and framing aren't too bad but it's a good idea to try some different angles. Some of them could be alittle brighter to reveal some more detail. You should also play around with the contrast of the photos to get a more realistic look. Lastly, you should definately increase the saturation on the photos. Saturation makes the colors more intense and more visually pleasing to the eye. Other than those minor things you have some nice photos here. If you have some spare time please drop by my gallery and leave a comment
