Is it possible to play these guitar and drums parts?

[NoAccess]

Hi everyone!

In my first song I tried to create guitar and drums parts to be possible to play but my friends told me they can't. Actually my friends are just studying but maybe these scores are impossible to play even being professional enough. If these parts are impossible to play what exactly is wrong with them? I want my next song to be completely playable.

First one is certainly not impossible. 1st chord in ms. 4 would bother some, also 2nd chord in ms 8. This latter chord is probably the most difficult. Classical guitarists encounter this kind of thing frequently.

I don't know what would be hard about yer drum kit part.
