Hmm, at first I thought my daughter might like that, but looks a little heavy?

The aluminium ones are often stated to be decent frames with poor/heavy components. Harder o find people's opinions of the steel frames, but it has proper dropouts and the welding looks alright. I would guess it depends whether you want to use the frame as a base and replace the overweight components.
