I'd say for playing 1 year, your pretty good. Your serve is very smooth, probably your best shot. Footwork is ok. Forehand needs more core rotation and less arm, also think about uncoiling your shot by bending your knees more, none the less, good stroke mechanics. Your backhand is your weakest shot. Your grip isn't right causing you to to lead with the elbow. This is VERY common with one-handers. I believe your talented enough to think about using an extreme eastern bh grip or the very least an eastern grip and keep that elbow locked through the stroke. As it is now, your grip is more for a slice.
