I agree with Wayne and Evan. It seems that most Spit kits, in all scales, can sometimes be a bit tricky to get that joint right. It's often a good idea to hold the wings in place with tape, from tip to tip, across the fuselge, whilst the glue sets. This will hold the dihedral angle (hopefully!), and help to set the faces of the wing to the root. As Evan has suggested, if you are able to split the joint, and re-glue, then it should work out well. If not, then just put this one down to the long, long learning curve!
The paintwork looks good so far, and what I could see of the cockpit also looks fine. Well done mate.
