Thanks for your replies!!!
Unfortunately I gave up for about a month, but I'm back into it again!
My rhytm is better now, but I'm still having problems with holding the pick correctly (it sounds so awfull, haha). I'm going to try a thinner pick, hopefully this will help!
ps: glad you liked Holland mansworth. Hope you also saw some flower fields, they're really pretty (I appriciate them more, now that I live in America!) :D
