I think the rose looks healthy but planting advice is generally that the graft union where your rose is joined to the root stock should be buried 1 or 2 inches below soil level as this increases vigour and reduces suckering from the root stock.
You may want to bear this in mind when the time comes to pot it on.
In the meantime, keep it well watered but not drowning. Feed it generously up until late June - no later as this encourages sappy growth that won't have time to harden off before winter frosts damage it. Consider a mulch of expanded clay pellets, slate chippings, chipped bark or some such to help retain moisture and prevent weeds.
