Vic,
the little piece looks outstanding for a first piece,
the dark discoloration, not that uncommon for a beginner, its from all the miles you put on it as you turned it over and over in your hands, and its picked up the dirt and oils from your hands, lots of miles on that project,,
spray it with rubbing alcohol and scrub it with a tooth brush, wipe off and do it again, it will clean up..
hard to do or remember to wash your hands before picking it up, keep clean hands and that wont happen...
the little man shows several styles one of flat plane carving in the style of the eyes, but im with you i would have to round out the features like you have, because
flat plane carving looks unfinished to me no matter who dose it , but then im just an old fart with another opinion.
Walmarts whittling wood manufactured by walnut hollow is some very non-standard basswood, the packages are clearly marked as they sell 2 different whittling wood bags here, one is pine and the other is some of the worst basswood i have ever carved, in a nutshell, you got to look hard to find the label as to which it is,
im currently carving my peewee's out of walmart's walnut hollow whittling basswood because it was easily obtained, last time i was in town., but im finding flecks and knots in it (something i have never found in henical wood) along with the wood not being from the same tree the density from each piece to the other is a wide spectrum from very hard to flakey soft. and in color as well, from white to flesh color.
wood from
Heinecke Wood Products have to be the best i ever carved, you order from them through email they send it and then they bill you later, so its convent to send them a money order or personal check,
i buy 2x7x12" blocks, and cut it with my scrollsaw but they have all kinds of precut wood. somebody told me they have grab boxes of pieces as well not advertised on their web site,
if you dont have a bandsaw like myself, i did go to a local cabinet shop and had them cut out several larger patterns i had, for a a nominal charge equal to a six pack was charged and i was in business,
i usually cut my own patterns out on my scroll saw but have resorted to a coping saw before i got the scrollsaw,
get some wood from heinecke and see the difference,
the odds of a beginning carver to come up with a carving good as you have made without a lot of experience , bad wood and hardly a decent knife,(exactos i think i heard you say) its hard to see how its possible but you pulled it off.
keep on trying your only going to get better as you get some decent tools and materials to work with.
