Only listened to the first track.

Mix wise this sounds a little muffled.
The kick could do with just a touch of definition in the top end.
the mid range percussion is a little fuzzy and undefined and could also be a little more solid.
Overal the mix and sounds withing lack width, clarity and presence.

Compare this track to some released stuff of good quality to get an idea of the size and fullness you need to achieve, as well as the fullness of dynamic range.

Better use of sompression and subtractive EQ is something to learn.
