Nice and interesting pictures. :D Here's a little feedback.
The background color and the shades of red on your Eevee are too similar. Try making the background color a much more lighter/darker red so that it doesn't look too similar to the red shadings on your eevee. As for the fur, try not to use criss-cross method because that may not be the best method to use when drawing fur. However, I will point out that I like the fur on the eevee's front left leg.
As for the second picture, I do like the coloring. It is just the anatomy that you may need to work on. For example, the eevee's left hand is much longer than the right hand. If you are trying to do perspective, use a few more lines on the arm to show that.
Keep it up. (:
