Write for MG readers and ready to sub right away?

If you've got a MG novel ready and raring to go but you want a couple of sentences of feedback on your query and first 10 pages of your manuscript then take a look at this page - it's only open until 5.30pm ET tomorrow (5th April 2019) and it won't be a lot of feedback, only a couple of sentences, but that's more than you've got right now and it's free, so what are you waiting for??
