Congrats on you're first try, Jimmy.
My first bit of advice, regarding the "chunk of cherry".
Even if you are making something that ends up with a lot of curves in it, and requires a lot of carving, you have to start by making you're chunks square. That is, all sides must be parallel to each other, and all sides must be square to each other.
Precision is a must. Looking at the top and botom lines of you're frog, they don't look parallel to each other, or straight. And the back doesen't look square to either of those lines.
So that would be where I would start. Think precise. think straight. Think parallel. think square. Think sharp. When you're making a frog, 95% of you're time is spent doing those things, the final carving and sanding and shaping, is only the final 5% of you're time.
And don't be discouraged. You have to make the first one, to see where to start improving.
Why not start another one today, and when it's done, put them both side by side in a picture so we can see the progress?
