from what I see, "aromatic" ( in the Hueckel type definition) has some conditions, "conjugated" being amongst them, meaning that there should be parallel p-orbitals at each and every atom of the cycle (so they can form one single delocalized pi-system)
those p-orbitals on individual atoms might be*) fully occupied (like the one bearing the negative charge in the cyclopentadienyl anion) , part of a bond (like all the C's in benzene) or empty (like the ones bearing the positive charge in cyclopropenyl, cycloheptatrienyl cations)
therefore, in a 4-membered ring with a single double bond and two positive charges, from my analysis the atoms bearing the positive charges should be the ones not involved in the double bond.
so, in my opinion, you've got that aspect wrong: those charges should be shown at the other two Telluriums
this , of course , is just a discussion of the hypothetical Lewis structure
in reality, these orbitals are part of the aromatic resonance system, and hence won't be empty (in aromatic cations) or "isolated, occupied" (in aromatic anions) as soon as you look into HOMO/LUMO schemes for the whole molecule
