Looks like you're going to be a natural!! It's obvious that you're enjoying yourself--my advise would be to play around for awhile, just as you're doing.. & then settle down and really study the craft & learn the tool..Very nice work for a start..
..landsbro did a beautiful painting with water droplets falling--check out his web site & you will see what this technique looks like ACED..it's very important to examine other art because you learn something everytime..
