I think the front wing, start from basics,
dont try adding all these fancy features yet until you understand them,
first start off I recommend with a basic wing profile, 2 or 3 elements to begin with and pull it across straight (no curving yet) and create these within the regulation front wing box, with outwash endplates (intersect faces with the endplate and delete the extra bit of wing) and add venturi s on the outer edges of the front wing,
if you run CFD on them you will notice a massive downforce increase if you do this, as at the moment, your front wings will not be making much downforce, but alot of drag,
