You're doon every bit of alright with them oily colors, lad. You're startin' oot with making it simple. And still it's lookin' full and descriptive like.
At this point, I will also make a recommendation t' expand yer range a wee bit by tryin' to use other colors for your line instead of only black and save yer darkest bits for the naturally occurring dark places, like yer beard . You can do the same thing, only try different colors and see what happens.
Nothin' wrong with what you're doing presently. It rocks. Boot, ye could creep up on a tonal paintin' that a-way, Mr. D. Crocket. We do need to get ye a raccoon pelt ta cover the pate like any proper explorer type, as ye are, laddie. We'll also have to get ye a guitar, and I think you'll be a sensation in the manner of Ricky Nelson. You can be come the Buskin' Ploos on the Brighton Boos, neh?
Carry On Paintin', oh aye. We'll add that to the litany o' Cary On movies.
All in the Ploos column. . . all to the good and mirthful. Great joy in it all.
