nice drawings for your beginning.
I think you have a good line stroke and is doing the hardest, to just copy without any tech.
You need to measure angles of your lines to get a good shape of your features, it keeps the drawing not so misled.
keep thinking of proportions for your drawings, try to measure with eyes and with guides(lines).
you will grow as you draw, I recommend ctrl+paint and drawabox for online tutorials.
For the second drawing, excellent depth and shading, the buttons facing the front looks rather misplaced or slanting downwards of the phone, Toribash logo seems to be within the screen rather than like an iPhone. I don't know if you erased it lightly but the last photo doesn't have the depth like the Wips, the final product don't look as good as the last Wipe but it's pretty good already.
