Listen to me! Listen to me! Trust ME on this one. I've been there. The next step up should, IMHO
, be Danger Dave's Dragon Blood Wine.

The first post on the thread contains the recipe. I dare you... No I double dare you to read the entire thread.
Kidding aside you'll likely make a very good tasting fruit wine for very little cost even compared to low end kit wines. I've made now three batches and have gifted close to two dozen bottles of Dragon Blood (DB) and have received only positive feedback and hints about maybe trying a second bottle. Two of the tree wine makers at church have asked for the recipe so that they can make their own batch of DB.
Another good choice for the next step up might be Skeeter Pee but I've not personally made that wine.
