To go after a seemingly orphaned baby dragon that manticore must have been from out of town...er forest, or he was desperate for a meal. Too bad for him though he betted his life for a meal and lost everything.
Great work, I couldn't tell that was your first manticore, I really like it's expression awkward moment mixed with total fear. And the baby dragon covering his/her face feel ambiguous to me. Obviously it would do so just when its about to get eaten but I feel like he's also covering his face cause he doesn't want too see his mom tear the hell out of that manticore (even though he/she is thankful that she did).
Nothing like a mother's love huh? You know? This probably isn't what the picture is, but personally that baby looks like a mixture of Jade and Spike, what with the spikes and wings, and that dragon's mouth looks similar to adult Jade's.
Again, probably a different dragoness and child, but this pic goes in my headcanon.
