Definitely see some improvement, specifically from top to bottom.
Try saving as a .png, for higher quality, as some of your tags look lq, or a bit too sharp.
I think those are just my style in particular. If your looking for depth and quality. I really don't have that down yet. Just down with creating tags with effects and lighting features. I happen to remain on a style that considers me to sharpen quite alot. PNG, files I only use as renders. I always was taught to save as an JPEG.
Thanks for the C&C either way.
