Comparison of my art

So, this may be a bit weird to understand, but if you watch me you'll see sometimes my art is cool and other times it looks like I was sleeping on my drawing tablet XD. Now I know I'm not completely horrible at art but I still get in moods where I think I can't draw n question why I draw for my hobby. It's not something I can stop but I do it.
And My art really reflects when I'm in this mood. Usually a day out or a day off helps me to get over it but I just wanted to explain it a little better.
It's sorta like my brain just thinks I suck so my hand starts to draw horribly. AND I Can't stop it. I usually just stop drawing and just take a break so I can actually feel my artworks again and make them how I love.But since I want to stay active and still get my work done I'm going to be forcing myself to finish so some of my art may suck once in a while.

Yeah that didn't really explain it all to well..
Here let me show you an example
You can see in the way my lines turn out and the eye really how I wasn't really getting to into it, and just wasn't happy while drawing it.
While with
You can see I enjoyed doing it a lot. keep in mind these are one day apart. I really got into it and loved doing it and still love it. (hm.. this is a painting and since I don't have any more sketch drawings to show you let me show you another example.)
and (the left one was actually made a week or so after the one on the right but same difference)
These are older but you can still see a difference. I forced myself to draw the one on the left while the one on the right came easily and freely. It's really weird that I can get in these weird moods, but yeah I do hopefully I can somehow get better about these moods or at least make better art during them.

Yeah just thought my weirdness needed a least a little explaining. I hope it kinda explains my random good to bad art.
I Don't want to just not draw during my moods cause then I'll never learn to get over them, And I also told myself I would post all my art even if I'm ashamed of it.
If you want more examples you can pretty much just go through my gallery. It's pretty obvious which ones I didn't feel compared to ones I love doing
