I was never one to be good at digital arts, I wondered it i could post my things from my sketchbook, but i think they're too messy and sketchy to be in the art portal. If i am post any of my stuff, i will most likely keep it outside of the art portal, is that right? i've never posted things before and i wanna get it right if i do!

If for 'too-messy' and 'sketchy' you're referring to the 'level' of your first submission (which that I've just given a quick 'glance'), I think that it'll be fine if you decide to submit them here as long as you mark them properly as 'sketches' (in case you were 'wondering' , yes, there's an option to do that which you can activate before submitting your drawings.)
Now well, as I'm not a Moderator of the Art Portal, in case that you still feel 'doubtful' regarding this topic, feel free to contact with one via PM, just in case.
