Wow, very well done!
I especially like your Mariko drawing.
I like the way you've handled the shading. And the blood gives it an extra edge.
A part where you might improve is the light reflection in the eyes. Maybe you could try to make the distinction of reflection and the eyes a bit less around the edges, 'cause the edges of the reflection stand out too much in my opinion.
And about the second pic: I'm not exactly sure which parts you've edited, but it looks quite nice. My only critism would be on the writing. It's not very readable at first sight, mostly because the blue f of "Myself" has a background which has the same colour. My advice would be to make it a bit less transparent or maybe change the colour of the font a bit, so that it stands out more.
Very well done :)
I'd love to see more of your work.
