welcome to tantra ... love the meshflow & little bit more on the anatomy sculpt & it will look great .
1 i think the chest part & the ribcage part need some sculpt
2. the tongue cant be that huge may be little thiner
i think overall u should start getting the organic feel muscle flowing into another
way to go
u r working nice . . . one thing - take a quick look to the similar anatomy creatures, then review ur characters anatomy .. . u will find some corrections required in the model.
