Docking a glycoprotein with a VH domain

To all it may concern,

My name is Matthew and I am trying to dock a sialoglycoprotein(CD24) with another protein for which I already have a decent homology model. I generated a model of the protein core of CD24 in I-TASSER, and was planning to add carbohydrates to the model later. However, the C score for the model was -2.4, and I am not sure if it is suitable for docking as I don't have much prior experience in protein modeling. I could really use an expert's opinion on whether or not my current model of CD24 will help indicate how it binds to other proteins in vitro. If the model is not sufficient, then I would really appreciate advice on how to create a more accurate model.

Thanks,
Matthew
