They both look like they needed a slightly higher shutter speed as they are both blurry. The first one could be a focus issue also. The second one the shoes are cut off and the bottom left is blown out.
Curious to why you set your ISo to 800 in the second shot. Both look a bit soft (out of focus) to me. The first one had potential to be a good shot but its oof and the white object top left is drawing my eye away. The second shot is just shoes that are shot from straight over top. Sorry these dont work for me.
A good start, but not without some areas for improvement. As noted in the above critiques there are some basics such as exposure and composition that you should start with.
