How can I make this pic solid black blackground?

I did an attempt at filling in paint but ofc its a fail and would take ages to outline the bits aorund the character it misses. ill do it if necessary not that much of a big deal however wondered if theres an easier way. Is photoshop the tool for this? If so how would i do it with that?
