The fact that it is in whole cross stitches only is a big plus.

The fact that there are 44 colors says to me that there will be lots of shading and colors that are very close to each other.

I consider myself somewhat experienced. T personally don't like changing colors often. If changing colors frequently doesn't bother you -- this should be a good project for you.

If you are an experienced stitcher this pattern will not be that hard for you. The use of 44 different colors of floss is really not all that many. Just take your time and you will be just fine.
