Probably not her best surface, but I still think Izzy has a bit of work to do on her game to catch up with the other top juniors, the likes of Katy, Katie, Eleanor and Harriet.
I think Izzy's ranking is a little misleading. It's basically all thanks to one great tournament (the recent 25k). I'm sure she's got lots of potential, and playing the top seed was always a huge ask, but she might need a little time to 'grow into' her ranking.
Her tweets about now being 100% focused on adult tennis, though, are very encouraging - and maybe there's another great tournament round the corner . ..
