There are 10 students in Liam's art class and 1/2 of them make a different amount of artworks than the other half, 1/2 x 10 = <<10-5=5>>5 students.
5 students make 3 artworks each, 5 x 3 = <<5*3=15>>15 artworks.
The other 5 students make 4 artworks each, 5 x 4 = <<5*4=20>>20 artworks.
Combined, the students in the class make 15 + 20 = <<15+20=35>>35 artworks.
